Hi Everyone,

I pulled the hover out of the garage today for the first time in

about 8 weeks. Didn't clean it down after it's last outing to

the beach. Oops - it's in suprisingly good nick considering it

was covered in sand, saltwater etc when i put it away.

The only thing that needs a lot of attention is the exhaust pipe

which is only about 6 months old. It's very rusty but mainly

just surface damage.

Apart from washing it down every time, what do you guys do to

prevent the salt causing too much damage to exhaust pipes when

running at the beach? It's off a rotax 447 - is it just a case

of keeping it washed and well painted?

Cheers, Craig

Simple really!!! http://hovercraft.org.uk/images/icons/smiley_icons/icon_cool.gif

As soon as scrutineering is finished put exhaust pipe in the boot of your car. http://hovercraft.org.uk/images/icons/smiley_icons/icon_rolleyes.gif http://hovercraft.org.uk/images/icons/smiley_icons/icon_biggrin.gif

a rotax engine will not like at all being left, with salty water and sand etc all over it!

rub the zorst down and paint it with holts fire spray, but i would say this is the least of your worries.

I have heard of a ceramic coating that can be applied that will stand the hot salt environment. Perhaps someone here can recomend a supplier?

I have tried a number of paints on the exhaust of my 503, including a professional job, but it all comes off when the salt spray hits it.

Osprey used to get their exhausts "hot aluminium sprayed" by a company in Sheerness Kent. I guess many coating companies around the country do a similar service. The problem with the company in Sheerness is that they had a minimum quantity rule. The would have to set up their equipment to do a batch which wasn't really economical when only doing one exhaust pipe. Anyway, it doesn't hurt to phone your local metal coating company to ask. Best get your local branch members to have theirs done at the same time.
